I don’t usually “see” the screwed up characters displayed in the command line. What I normally experience is the commands show up in the dynamic input “tooltip”-commandline but it only takes the first letter because there’s some kind of delay. Like I’ll type “ex” for extend (and see both letter display), then hit the right mouse button to enter it, and it’ll only use the “e” and start the erase command. SOOO ANNOYING!

(The “always” comments on 2, 3, and 5 simply means that is how my system is configured, not that the problem doesn’t happen in other modes)

As far as the actual scenario you are talking about, it seems like it occurred more often back around the time of R2000-R2002, but it still happens today.

I have a much larger complaint about the generally slowness of the application in general. I can repeatedly click the application window in 2010, and it takes 0.5 second each time. That doesn’t sound like much, but it should appear instantly. Because it has that little delay, it makes it “feel” much slower. The drop-down button component of the QAT acts the same way.

The Ribbon is deathly slow, at least the first time through each tab. Once you have visited each tab, the response time is acceptable when switching between them. But what really annoys me is when another application has focus, then you move the mouse over the AutoCAD “minimize” button. The button changes color, which indicates to me that AutoCAD knows the mouse is there, but when you click – all it does is switch focus to AutoCAD and you have to click the button again. No other Windows application behaves like this.

1. AutoCAD and AutoCAD Map3D (that’s what I use now and where I have seen it the most) both 2009 and 2010 of each.
2. Command line docked.
3. Dynamic input status:on, I almost never turn it off.
4. Screen configuration: currently single.
5. AutoCAD main window status: maximised
6. Yes, from time to time.
7. No.
8. Windows XP Pro, Intel Core 2 Quad, 2.4 CHz, 3 gig RAM
